For those who are curious, it's called "Box Breathing" because, if it's helpful for you, you can picture a box and then trace the edges of the box in your mind as you're counting for each of the 4 steps (inhale, hold, exhale, hold). That visual can help take your mind off whatever is making you do this in the first place.
In parallel computing, similar topologies are known as the Hypercube architecture. And in English, "boxes" can refer to computers or networking devices in general, so yes? ;-)
